Contact toxicity of Essential Oils from Tithonia diversifolia against Aphis gosypii, Thrips tabaci and Bemisia tabaci

Plants and microbes provide naturally occurring chemicals that are often used for the control of pests all around world. Biopesticides have been as a comparatively safer replacement synthetic pesticides past five decades. This study determined contact toxicity essential oils from Tithonia diversifolia plant against Thrips tabaci, Bemisia Aphis gosypii. The (Eos) were extracted dry leaves by hydrodistillation using Clavenger apparatus 8 hours. GC-MS was utilised to analyse qualitative quantitative composition oils, whereas ATR-FTIR employed determine functional groups. 3-Carene most abundant compound ion in Eos. T. B.
